Arguments:

### Details

qmlformat is flexible and can be configured according to your needs.

#### Output

qmlformat writes the formatted version of the file to stdout. If you wish to have your file updated in-place specify the `-i` flag.

#### Grouping Properties, Functions, and Signals Together

With `-n` or `--normalize` flag, qmlformat groups all properties, functions, and signals together, instead of retaining the order you specified.

#### Settings File

You can configure qmlformat by including a settings file `.qmlformat.ini` in your project source or in the parent directories of your project source folder. A default settings file can be obtained by passing the `--write-defaults` flag. This generates the `.qmlformat.ini` file in the current working directory.

Warning: `--write-defaults` will overwrite any existing settings and comments!

#### Formatting a List of Files

While you can pass a list of files to be formatted as arguments, qmlformat provides `-F` option to format a set of files stored in a file. In this case, formatting will happen inplace.

     // FileList.txt
     main.qml
     mycomponent.qml

Then, use it like

     qmlformat -F FileList.txt

Note: If the file contains an invalid entry, for example, a file path that doesn't exist or a valid file path but the content is an invalid qml document, then `qmlformat` will error out for that particular entry. It will still format the valid file entries in place.

Warning: If you provide -F option, qmlformat will ignore the positional arguments.
